    Serengeti Panther just dies until i unplug/plug the battery back in

    Hey OP, did you ever figure this out? And can you tell me where you got the battery from?

    Serengeti Panther: is COTS Battery an Option?

    Thanks for looking out Elektrosherpa, that does indeed look scary. I have already fitted the new battery with an Anderson plug as recommended here. The charger is C13/14 but I think it only charges at 2-4A. My previous comment has the latest update and three new questions.

    Serengeti Panther: is COTS Battery an Option?

    Update and questions ... I have soldered the Anderson plug and the charger plug onto the battery wiring, as instructed by BtrPower: Small black + red wires --> charging (C14) Thick black + red wires --> power (Anderson) I have two questions: 1) The original battery had a yellow wire running...

    Serengeti Panther: is COTS Battery an Option?

    FWIW neither I nor any of the coworkers I have asked have ever had to take an integral or derivative in the course of our regular work. But it would have been impossible to get through engineering school without them (sadly).

    Serengeti Panther: is COTS Battery an Option?

    Amberwolf, For what it's worth, my conversations with you have been virtually indistinguishable from those of my coworkers who are electrical engineers (I'm an engineer but not a EE). I think you would make a highly, highly skilled EE, and the right place would not mind that you prefer to be...

    I can not understand how there is no such thing as an Anderson to IEC C14 converter. Do my google and Amazon searches deceive me?? How could something so simple not already exist?

    Serengeti Panther: is COTS Battery an Option?

    Ok, so obviously I need to have two plugs here since I do not want to set my derriere on fire :flame: :) . Let me work on that and report back. BTW, I don't know what you do for a living but if you aren't already an engineer, you would make a GREAT one! I'm on it! Thank you both!

    Serengeti Panther: is COTS Battery an Option?

    Update! Battery came ... there are four wires ... two thin and two thick. I am supposed to solder connectors to it this way: Instructions say: Solder two thin wires to regular C14 connector (used for charging) - red thin wire --> solder to positive side of C14 connector - black thin wire -->...

    Amberwolf, I put in an order for "OPTION B" on Amazon. It should arrive in about a week. I will report back... Tara

    Serengeti Panther: is COTS Battery an Option?

    Thank you Amberwolf! I posed the following question to the seller about OPTION B battery: This was the seller's response: (Bit annoying, the page says 50A BMS, and now they are saying 40A. However, if the controller says 30A maybe it is ok...) Please tell me if you think I am making a big...

    Serengeti Panther: is COTS Battery an Option?

    Thank you Amberwolf! Sounds like OPTION A battery won't work for me because the controller needs 30A constant discharge current (assumption because we don't know for sure) and this one only goes to 20A. I'm guessing the 30A max current is peak (for hills) because it is a fairly light scooter...

    Serengeti Panther: is COTS Battery an Option?

    I found this 48V 15Ah 500W battery online and I think they might even be willing to swap the connector to a C13: https://amzn.to/3tnQlIn [Edit: I am referring to this one as OPTION A] Lithium Ion 48V, 15Ah, compatible with 200-1000W BMS: 20A Max Constant Discharge Current: 20A Peak Discharge...

    Serengeti Panther: is COTS Battery an Option?

    Yes, I was looking for 48V LiFePo4 but I think I also looked at 48V Lithium Ion as well. Where do you buy your batteries from?

    Serengeti Panther: is COTS Battery an Option?

    Good grief, this is so frustrating. I'm trying to find batteries online. I googled, ebay, amazon ... there are a bazillion no-name Chinese outfits with 1-2 reviews. The ones that have a lot of reviews meet the "well, I couldn't find anything better" list and most don't explain what kind of...

    Serengeti Panther: is COTS Battery an Option?

    I read through your post about 10 times ... so much great info in there. Thank you so so much (have I said that already?) So I am looking for a 48V 15Ah 500W (found that spec online) LiFePO4 battery - with balancing BMS - 500W/48V = round up to 11 Amps (but it looks like I order by Watts) -...

    Serengeti Panther: is COTS Battery an Option?

    Thank you so much for getting back to me! Wish I'd seen your response yesterday... sorry for delay. I have checked the "Notify me" --chemistry (to know if existing charger could work): Lithium Ion --full voltage, empty voltage (average voltage plus chemistry will also tell us this) (48v...

    Serengeti Panther: is COTS Battery an Option?

    Been lurking here for a while and I'm finally in a position to be able to ask for help... My Serengeti Panther scooter ran fine initially, and slowly the battery was dying sooner and sooner until one day when I had to walk the scooter home as my poor little champ could not even get me where I...
